PERI takes on Grand Designs project

Oct 25, 2018

PERI’s latest formwork system, DUO, has been used to construct a unique self-build project in East Sussex.

Concrete House, developed and owned by Adrian Corrigall, aired on the popular TV series, Grand Designs, on 24th October 2018.

The cast in-situ structure features an exposed concrete finish and varying floor heights throughout. From the onset, it has been a case study for simplifying construction methodologies, whilst also providing a family home. All aspects of the construction process, such as the choice of formwork and the concrete mix, have been experimental.

PERI provided ongoing technical, sales and field support to deliver the architect’s vision of Concrete House. This involved producing accurate technical drawings supplemented by on-site supervision to ensure DUO achieved a consistent tie-hole pattern and panel arrangement across all walls, as well as irregular shapes in some parts of the structure.

DUO was selected for its ability to form all aspects of the concrete structure, including slabs, columns and walls. The versatile system also aligned with Adrian’s vision of reducing waste during construction. All of the raw material is 100% recyclable and can be reused in the production of new panels, which made it a sustainable alternative to using conventional formwork on this project. Due to its light weight, the system also offered logistical benefits. Only three lorries were required to deliver material from PERI’s depot to the site.

Developer and owner of Concrete House, Adrian Corrigall, said: “DUO works in perfect harmony with the experimental concrete mixes we are using in that both reduce labour and material costs, reduce the project’s carbon footprint and are definitive steps forward in construction methodology”

Note to editors

DUO is a lightweight technopolymer plastic formwork system. With no component weighing more than 25kg, DUO can be manoeuvred around construction sites with ease. Optimisation is a key benefit of the system’s design, as it can be used to form walls, columns and slabs with reduced tooling requirements. It’s 100% recyclable, making it a sustainable option for any construction project. The formwork system reduces the output of waste as it is reused in the production of new panels and components.
